NELSON NElVMAN, OF SPRINGFIELD, ILLINOIS, ASSIGNOR OF TWOJIHIRDS TO GEORGE A. SANDERS AND SAIIIUEL J. VILLETT, l-lOTI-I OF SAME PLACE.

AUTOMATIC GAS-EXTINGUISHER.

SPECIFICATION forming part of Letters Patent No. 425,953, dated April 15, 1890. Application filed September 30, 1889. Serial No. 325,550. (No model.)

To ctZZ whom t may concern:

Be it known that I, NELSON NEWMAN, of Springfield, county of San gamen, State of Illinois, have invented a new and useful Im- 5 provement in Automatic Gas-Extinguishers;

and I do hereby declare that the following is a full, clear, and exact description of my invent-ion,which will enable others skilled in the art to which it pertains to make and use it,

1o reference being had to the accompanying drawings, forming a part thereof.

My invention relates to an improvementin automatic gas-extinguishers adapted to be used on street-lights and for other similar r 5 purposes; and it consists in thepeculiar construction and combination vof devices that will be more fully set forth hereinafter, and particularly pointed out in the claims.

In the accompanying drawings, Figure l is 2o a side elevation, partly in section, of an automatic gas-extinguisher embodying my improvements. Fig. 2 is a transverse sectional View of the same, taken on the line :o fr of Fig. l and illustrating the construction of 2 5 the clamp. Fig. 3 is a similar view taken on the line y 'y of Fig. l.

In. the box A, which is rectangular inform and of any suitable size, is arranged a suitable elock-work mechanism or other motor,

3o (not showin) the shaft o. of which is adapted to rotate once in twelve hours. To the outer end of the said shaft is affixed a circular disk b, having a series of twelve openings c near its periphery, arranged at regular distances 3 5 apart and numbered, as shown, to indicate the hours. A tappet-pin CZ is adapted to be inserted in either of the said openings for the purpose to be presently described.

The gas or gasoline pipe has two sections 4o e f arranged at right angles to each other and connected together by the coupling g.

To the upper end of the vertical section f is attached a burner 7L, which may be of any desirable construction, and the said burner has a threaded opening fi at right angles t-o and intersecting its bore. In the said threaded opening is arranged a screw-cock Z, having at its projecting end an arm m. W'hen the said cock is turned in one direction, its threaded stem moves outward and opens the 5o bore of the burner to permit the iiow of gas therefrom, and when the cock is turned in the reverse direction its threaded stem closes the bore of the burner and cuts off the flow of gas, as will be apparent.

To the lower side of the box is attached a cylindrical clamp n, having the hinged lower member 0, which is adapted to be opened to receive the horizontal section c of the gaspipe and to be closed on the same. Lips 17 6o are formed at the cuter sides of the members of the clamp, and a bindingscrew r engages threaded openings in said lips, and serves thereby to clamp the sections securely on the pipe, and thereby attach the appa* 65 ratus iirmly thereto. It will be noted by reference to Fig. l that when the apparatus is thus arranged in position the arm Z of the cock is in the path of the tappet-pin, so that when the disk is rotated t-he said arm 'vill 7c be engaged by the said pin. Before the gas is lighted the cock must be turned by hand to the open position, and the clockwork mechanism being set in motion the tappetpin will be placed in the opening eorre.- 7 5 spending to the hour at which it is desired to extinguish the light. Te will assume that the ninth hour is selected and the pin inserted in opening 9. This being done, the How of gas will be permitted until the allot- 8o ted time has expired, when the revel 'ing disk will bring the tappet-pin in contact with the arm I, and as the said pin passes the said arm the latter will be caused to turn the cock to the closed position, and thereby extinguish 85 the light.

Having thus described my invention, I claim#- 1. The automatic gas-extinguisher com prising the box having the clamp to secure it 9o to the gas-pipe, and provided, further, with a time mechanism having the revolving timedisk h arranged on one side, said time-disk having the openings c and the tappet-pin ad v justable in said openings, and the burner justable in said openings and arranged in the having` the cock provided with the arm m arpath of the arm m, substantially as described. 1o ranged in the path of the tappet, all adapted In testimony that I claim the foregoing I to operate substantially as described. hereunto append my signature. 5 2.
